BiologySchooling species, adults inhabit sheltered lagoons, harbors and inlets. Also in somewhat open substrates with outcrops of Acropora corals (Ref. 48636). Often associated with small coral heads. Feed on a variety of plankton, including larval shrimps and crabs, algae, ostracods, amphipods, pelagic tunicates, copepods, and fish eggs. Oviparous, distinct pairing during breeding (Ref. 205). Eggs are demersal and adhere to the substrate (Ref. 205). Males guard and aerate the eggs (Ref. 205)..
